There are different models at different price levels. I got the 900 at 429.00. I think what they've done is dropped the price on what was the top level model, and then cranked up a premium price for a model with a dryer and odor control, which ultimately subsidizes the cost break, and makes it easier to sell more without a more drastic price decrease. When i first looked into these things more than ten years ago, they were all over a grand.
